IMPROVEMENT OF FOURIER-SERIES ANALYSIS TECHNIQUE BY TIME-DOMAIN WINDOW FUNCTION

We demonstrate that by adding a time-domain window function to the rec ently developed Fourier series analysis technique can reduce the propa gation error in solving the nonlinear soliton propagation equation, Wi th suitable modification of window function parameters, the number of sampling points as well as computational time required for the calcula tion can be minimized even with higher order dispersion terms taken in to consideration.
